N2 - Two different N-containing austenitic stainless steels were aged at temperatures from 600 to 800 °C for 10 to 1000 min in order to study the precipitation kinetics. In general, the fastest precipitation occurred in the aged steel with higher content of interstitial solutes, named 24Cr-15Ni-4Mn-0.32N-0.04C steel. Time-temperature-precipitation, TTP, diagrams showed that the intergranular precipitation of M23C6 and M2N preceded to the intragranular precipitation of M2N and M2N and η phase in the aged 24Cr-15Ni-4Mn-0.32N-0.04C and 12Cr-12Ni-10Mn-5Mo-0.24N-0.02C steels, respectively. Besides, the presence of cellular precipitation of austenite and M2N was observed to occur in the aged 24Cr-15Ni-4Mn-0.32N-0.04C steel.
